Pune: The Defence Institute of Advanced Technology (DIAT) has developed a biodegradable face mask based on Nanofibres of Ayurvedic products which acts a virus neutraliser and resist the bacteria.

This mask has been named as “Pavitrapati”. The mask is made from herbal extracts like neem oil, turmeric, krishna tulsi, ajwain, black pepper, gum arabic, clove, sandalwood and saffron. 

Keeping in view of the Ministry of Ayush guidelines, “Pavitrapati” uses additives from immunity boosting agents for self-care.

According to a statement put out by DIAT, “The product is antibacterial, antifungal, antiviral, porous, superhydrophobic (outer layer), hydrophilic (inner layer) and biodegradable. This technology has proved that non-woven membrane between the woven fabrics supports to block droplets, splashes, sprays, bacteria and viruses. This product shall be used routinely as a mask to protect from any type of communicable diseases through an air-borne medium.”

“The 3-layered mask provides antiviral potential because of the interaction of extract to inhibit viral neutralisation. The product will be extended for infection prevention and control measures as Personal Protective Equipment (PPE) and waste management materials. This will consist of garments, gloves, gown, face protection, head cover etc. The product is foldable and can be used as a mask in cleanrooms of various classes. The fabricated samples were tested to understand the de-naturing capability of the protein molecules by NMR, and the results demonstrated that the natural herbal extracts interacted and de-natured the aminoacids,” DIAT has stated. 

DIAT has decided to offer this technology free for the cost to potential manufacturers, and many firms have shown interest for the same.
